Uncertainty In Combustion Reaction Rates And Its Effects On Combustion Simulations, Joshua Piehl
Uncertainty In Combustion Reaction Rates And Its Effects On Combustion Simulations, Joshua Piehl
Wayne State University Theses
This work investigates the uncertainties in reaction rates of an n-dodecane model on turbulent spray combustion simulations. Six major reactions were found to significantly impact the ignition delay of the mechanism in a 0-D batch reactor model. These reactions’ rates were independently modified and placed into individual mechanisms. These newly developed mechanisms were simulated in a 3-D turbulent spray simulation and a 0-D batch reactor at a pressure of 60 bar and temperatures from 900 to 1100 K. The combustion characteristics (e.g. ignition delays, flame lift-off length, liquid and vapor penetration) of the modified mechanisms were compared to those produced …
